I've looked on-line for a way to edit individual images on MP4s in C# and found nothing.
so, I'm resorting to playing the video full screen in a WindowsMediaPlayer and screen capturing as many images as I can.
the results are good but botchy. So I shut-off my WiFi and disabled services.sysmain to help it along and have mixed results.
for the same 3m40sec MP4 video my screen captures range from 800-1200.
the best times capturs images and stores them on the HD in a binary-stream file as it goes along
- average = 1200 frames
alternate method:
instead of capturing an image and saving it to the HD in the binary-stream file right away I kept them in a list and only saved them to the HD after the video was over. thinking that going to the hard-drive was slowing everything down (the WMP
is retrieving the video from the HD and my binary-file-stream is on the same HD) I assumed storing the data in RAM while the video played would speed things up but doing that only gave me on average about 800 frames for the same 3m40sec video.
summary:
- storing each frame to HD as they're captured results in 1200 frames
- storing each frame in RAM as they're captured results in 800 frames
how is that possible?
my code is perfect until i don't find a bug
